Abstract

One method for the development of the mechanical properties of composites is to integrate different substances into the polymer matrix to improve mechanical and erosion properties. In our paper, dolomite is recommended as an additive to improve the properties of fibre-reinforced epoxy composites. The analysed composites were developed in a wooden mold by using conventional handlayup procedure. The dolomite-ﬁlled fiber reinforced composites were evaluated for physical and mechanical properties. Densities (both experimental and theoretical) and void content of manufactured composites were found to increase with increased dolomite content. With the addition of dolomite, the hardness improves with a decrease in tensile strength.
